Studio 4DGS - Effigy 3D

A 4DGS studio
to shoot in 3D video

4DGS is the Gaussian Splatting of video!

In early 2026, EFFIGY will open a studio optimized for 4DGS volumetric video shooting…

located in our offices in Paris 15,
of adjustable size and layout,
No green screen, free lighting
and transportable throughout Europe

With fifty genlocked 4K cameras, it combines the image quality of a traditional video production with the full potential of virtual production to create hyper-realistic 3D content.

The 3D videos thus generated are compatible with the main virtual production software: Unreal, Unity, Blender, C4D, Houdini, After Effects…

Two options for integration into your applications:
– in flipbook format = a series of uncompressed Gaussian Splatting images; this is the ideal workflow for video post-production
– encoded in .Mint, Gracia's format = lighter, and well-suited to XR productions / interactive applications

What is 4DGS?

Volumetric Capture, the technique that merges Video and 3D
Volumetric capture transforms the way we film reality; unlike traditional video which captures flat images = in 2D, it captures the full volume of a scene — depth, movement, texture — and creates true 3D videos = spatialized video scenes, in photorealistic quality.

With 4DGS, Gaussian Splatting boosts Volumetric Capture
4DGS (4D Gaussian Splatting) reconstructs each frame of a scene with millions of Gaussian "splats"—3D primitives, each possessing its own position, orientation, color, and opacity. The "4D" prefix adds a temporal dimension to the spatial dimension of Gaussian Splatting; movement is captured and rendered with its natural fluidity.

Decisive advantages for post-production and XR!
– Photorealistic quality: Exceptional reproduction of micro-expressions, skin translucency, light interactions — this surpasses all other 3D animation techniques.
– A revolution for video production: Once captured, the performance can be edited from any angle, a virtual camera can be freely moved around the scene in post-production, the lighting can be adjusted, and even special effects can be applied.
– Total creative freedom for the XR: with 4DGS, it is now possible to integrate the actions of filmed characters into full 3D scenes

Concrete applications in several sectors
– In cinema, 4DGS allows for ultra-realistic digital doubles and a virtual production that is much simpler and more natural than Motion Capture animation work on Avatars.
– For video games, it offers characters of unprecedented realism, beyond AAA!
– In VR/AR, it establishes a disturbing human presence in increasingly realistic virtual scenes!

And beyond the entertainment sector, 4DGS technology will transform professional training (interactive consultation of gestures from all angles), education (virtual lecturers) and cultural heritage (preservation of artistic performances).

4DGS and Artificial Intelligence
In another vein, 4DGS also makes it possible to generate exceptional training data for Artificial Intelligence = a holographic "ground truth" allowing learning models to ingest and reproduce human movement accurately, while preserving its emotional authenticity.

Thus, 4D Gaussian Splatting is not simply an improvement on 3D animation techniques: it is a paradigm shift where the boundary between real and virtual blurs, and this will profoundly enrich visual creation and future virtual worlds.

A modular film studio

Effigy designed this modular studio, which means that…
– the size is variable, for filming in close-up, portrait, full-length, or with several people on screen
– The camera layout is completely customizable, to make the most of Gaussian Splatting depending on the 3D navigation scenario
– the lighting is also completely customized (unlike traditional photogrammetry which requires flat lighting)
– the equipment is transportable to another filming location
